=Why is it in grave danger?= =What are some environmental issues?=
 * From [|www.dictionary.com], environment = //Ecology// . the air, water, minerals, organisms, and all other external factors surrounding and affecting a given organism at any time
 * For the past decades, humans, in the name of advancement of technology, has taken the Earth's resources for granted and have not been treating Mother Nature with respect. Natural resources such as oil, coal will soon be depleted and the excess greenhouse gases such as carbon dioxide and methane have trapped heat in the Earth, leading to the increase of global temperatures and the increase in natural disasters.


 * Factories have been releasing toxic gases into the air, leading to ozone depletion and acid rain which corrodes buildings.
 * Factories also release toxic waste into the sea, destroying marine habitat, such as fishes and coral reefs
 * Humans have cut down trees in order to get land for farming, building and other purposes. With lesser trees to absorb carbon dioxide, there are excess greenhouse gas in the air.
 * Deforestation also causes soil erosion that causes landslides or pollute the rivers around it.
 * Some woodcutters used the "slash and burn" method due to its cheapness and easy-availability, however, burning away large areas of land will lead to serious air pollution, haze, and smog.
 * Clearing away of forests and land reclamation will also destroy habitats of animals, leading to the extinct of animal species.
 * Intensive farming will also lead to loss in soil nutrients. When farmers desert the land, the land is left to rot and desertification occurs, resulting in loss of arable land.
 * Polar ice caps in the north and south were seen melting in huge chunks during the summer but ice caps are not forming enough during the winter, leading to rise in sea levels. Example, water is rising so quickly that the Maldives is drowning. President is asking residents to evacuate.

 * How do we protect the environment?**
 * **3Rs - Recycle our resources such as using water used for washing rice to water the plants; Reuse shampoo or shower foam bottles; Reduce the usage of plastic bags**
 * **Switch off all electronic devices when leaving the room**
 * **Use environment friendly items that do not contain hazardous chemicals like CFCs**
 * **Reduce the use of pesticides or insecticides unless they are labelled "Environment Friendly"**
 * **Use fluorescent lamp instead to save $$$ and energy**
 * **Keep temperature of air-conditioner at 25 degree Celsius or don't use at all. (Using the air-conditioner 8 hours a day for 31 days is $52. Using the fan 8 hours a day for 31 days is just $3!!)**
 * **Do not open the refrigerator or fridge without any reason**



= = = = = Kester - This wiki has useful information on how to protect the environment and issues on global warming. these points are clear and conscience. the only thing missing i would say were case studies on how badly global warming is affecting us. some statistics would be helpful. = Teng Hui - I feel that the group could give some examples of large groups or companies doing their part to save the environment instead of only what the individuals can do to save the environment

Delwin - Good: covers issues on environments, and how natural resources will be depleted, and the relationship between man and nature. global warming is also covered to some extent Missing: statistics are given on how we can protect the environment, but not how the environment affects us(e.g. global warming and desertification etc), survey/statistics of how many people help to protect the environment Organisation: Environmental issues coupled with statistics would help. Intro Environmental issues Impacts on humans Statistics

Bryan Kor - This group had covered about most of the important points in the topic, it is very clear and easy for us to refer to and find what we will be needing to read up for our examinations. The information provided is also very adequate and relevant to us students for us to apply during the examinations.

- However, i feel that this group had only covered the immediate consequences of environmental issues and may want to consider adding in how these issues will affect us in the long run. Also, they could add on more concrete statistics which will be able to help us to substantiate our argument during our essay writing.

Nigel - It provides very relevant information, and it is also well-explained. It also has clear headings and is also very easy to read. It will certainly help as notes for exams

- They can still improve, by giving examples, to support their facts. Case studies and some statistics will help our arguments in essays.

Jun Xiang -I feel that the team has done a great job with the organization of the flow of information for this wiki page. The team focuses more on the areas that are relevant to our examinations e.g case studies of environmental issues and less on the background info e.g what is the environment, which is not necessarily important for our examinations. The team has also provided adequate examples that we can utilize in our essays..

-However, the team talks little on the things that can be done to combat global warming. Other than the things we can do as individuals, the team does not mention about the role companies or countries play in the combat against global warming, e.g the Kyoto protocol. Providing us with these information is essential, as questions on global warming can include the involvement of major companies and countries. Also I feel that there is a lack of statistics. Facts coupled with numbers would definitely allow the points mentioned in our essays to be more substantiated and concrete.
